Hi Francois,
I'd run LOGTOOL and list the current and just prior log with the following:
LOGTOOL
LIST LOG=curr/curr-1;TYPE=111;OUTFILE=DISK0203.DIAG
EXIT
Then go into EDITOR and
SET DELTA=.001
T DISK0203.DIAG,UNN
C/PDEV/,/PDEV/,all
And look for errors other than tape or DTC...you should see channel timeouts/retries if it's in the disk subsystem.

Subject: [HP3000-L] Disc problems on an A400-100-11 HP3000
We have been experiencing sporadic problems on our A400-100-11 over the last 2-3 days. It works normally for a while then it goes down to a crawl. Logins, running programs, uploading files with ftp, etc., everything takes forever to complete, if ever. We have not been able to identify a specific. It just happens.
In case this may help, here's a DISCFREE C output:

Glance is telling us the CPU is Pausing (75%) and disc is High. However, the Disc statistics are showing low numbers, below 10. We suspect one or many discs are having problems.
If the whole system slows right down, could this be the controller?
Is there a way to see the I/O queues and maybe determine which disc needs to be looked at?
Any tool available to check individual discs? E.g. SCSI driver/diagnostic
Any other ideas/suggestions?
Thanks...François
